org.jikesrvm.compilers.opt.specialization
Class InvokeeThreadLocalContext

java.lang.Object
  extended by org.jikesrvm.compilers.opt.specialization.InvokeeThreadLocalContext
All Implemented Interfaces:
SpecializationContext
public final class InvokeeThreadLocalContext
extends Object
implements SpecializationContext

This class represents a specialization context meaning "the invokee is thread local". We use this context to remove unnecessary synchronizations.

          The default optimization plan.
private static OptOptions options
          The default optimization options, with the INVOKEE_THREAD_LOCAL flag set true.
 
Constructor Summary
InvokeeThreadLocalContext()
           
 
Method Summary
private  SpecializedMethod createSpecializedMethod(NormalMethod method)
          Create specialized method in this context.
 SpecializedMethod findOrCreateSpecializedVersion(NormalMethod source)
          Find or create a specialized method in this context.
static void init()
          Initialize static members.
 CompiledMethod specialCompile(NormalMethod source)
          Generate code to specialize a method in this context.
